F91 seemed like it might get an MG release someday, yet also felt like it never quite would — and now here it is. F91 was considered a somewhat unpopular unit from a somewhat unpopular anime, so making it into the MG lineup is quite an honor in its own right — though in another sense, it probably also means Bandai is starting to run low on source material.
The MG F91 tries a lot of new things compared to previous MGs in many respects. It also has some unexpected design choices that feel a bit out of left field, making it a pretty unique kit overall. The problem is that some of these new attempts feel awkward, and at times even a bit over-the-top — to the point of being a little baffling.
▶ Things that feel somehow new.
1. Polycap elimination
For the first time in well over a decade since Bandai adopted the polycap joint system, the MG F91 has been released with a structure that completely eliminates polycaps. You might wonder what kind of backwards thinking led to this — but according to Bandai, the reason is to prevent joints from gradually loosening over time due to the polycap structure. They've implemented the frame using only ABS joints, in what they call a "polycap-less" approach, expressing their intent to keep joints from going slack even with regular use, thanks to ABS joint mechanisms that wear down less.
Even before this, recent new releases had been quietly dropping polycaps from key joint areas one by one, with polycap usage gradually declining — and now they've gone ahead and removed them entirely. As a result, the joints throughout the body are noticeably stiffer, and the assembly process has a bit of a strained feel to it as well. ^^;
After repeatedly moving every joint on the body for the review.. I'd say joint strength retention is a pass for now. Without polycaps there's no smooth, buttery feel to the movement, but aside from a few spots, the joints don't really feel like they loosen up much even after repeated posing. Of course, if you move them an insane number of times they'll loosen a bit, but it does seem like the joint strength will hold up longer than polycaps would. That said, the stiffness is a bit much and there's no smooth feel to it, so most people will probably find it hard to get used to. ^^; Roughly speaking, it's smoother than the joints on the G Gundam MGs that had reduced polycap usage, but stiffer than standard polycap joints.
2. Odd color separation
It's strange. Genuinely strange. ^^;
Why strange? Well, the usual approach has been to split parts in a sensible way to achieve the intended colors — but this kit actually force-splits parts that would've matched the intended colors just fine on their own, and then molds them in the opposite color instead. The front skirt armor is one such area, and it's a surprising choice by Bandai's usual standards. In short, it's not a technical challenge at all to get the right colors here — it feels like they just went "we're doing it this way!" and ran with an overly clever idea for its own sake.
And yet at the same time, color separation on small parts that you wouldn't normally expect to be separated has actually increased. The small yellow triangles scattered all over the body are a good example — these are the kind of details that would normally just be handled with stickers. They're very small and thin parts, the kind that usually don't get color-separated as a cost-cutting measure... This is probably influenced by Kotobukiya's mech kits. Kotobukiya's recent Super Robot Wars/Armored Core mech kits have been showing off impressive color separation down to very tiny details, and Bandai may well have been thinking "there's no reason we can't do that too."
Either way, it's a rather confusing color separation policy. -_-; So I was going to do at least some partial painting myself... but in the end I just painted the shield, which was the most glaringly obvious spot, and called it a day. Nom nom. Meh.
3. New hip joint
Since the PG Strike, the hip joint structure (where the body connects to the legs) had been evolving in recent MGs. The hip mounting point would swing forward and backward, and at times each leg could even move forward and backward independently. It was a fresh idea in its own way, and it was genuinely effective for poses where the legs are raised far forward. So it was reasonably well-received — though there were also complaints that the joint was a bit ambiguous to lock in place after posing, and that there were some durability concerns.
With this F91, yet another new hip joint structure has been tried — and it's changed from the previous articulated hip design to a simple fixed type. Instead of the pin connecting the leg to the body being centered in the middle of the leg, the fixed pin is offset toward the front of the body, which produces the same effect as having a forward-shifted hip joint when you raise the leg upward. On top of that, the normally ball-shaped hip joint is split horizontally, allowing the legs to kick out sideways up to 90 degrees.
This structure is implemented simply with just two parts, but the actual effect on articulation is excellent. The legs can swing forward naturally and quite far, while also spreading wide to the sides — so it delivers surprisingly efficient articulation for such a simple design. It makes you wonder why they didn't do it this way sooner. It's a bit anticlimactic, in a way, that such a simple structure outperforms the old articulated hip joint. ^^;;
4. PG-level frame detail
Recent MGs have mostly featured near full-body inner frames with increasingly refined detail. But the MG F91 pushes the detail to the absolute limit of what a model this size can offer. Among all existing Gunpla, it's safe to say this kit is at the very top in terms of frame detail density per unit area.
The arm and leg detail is just a notch above average, but the double and triple layered frames in the body are clearly PG-level detail — and considering it's much smaller than a PG, you could argue it surpasses PG in that regard. Seeing it in person, the detail is so incredibly dense that you can't help but be impressed. It makes you think Bandai has lost their minds.. ^^;
It's almost hard to understand what possessed them to layer in this much craftsmanship, but as a Gunpla fan it's absolutely something to welcome. What's especially remarkable is that even the beam rifle — which tends to get overlooked at the MG level — has been given an ultra-precise inner frame. This is full-on PG territory. And the exterior detail on the weapons feels a little sharper too.
Thanks to all that densely packed, layered detail, the kit feels completely solid and stuffed to the brim. :-)
5. Diorama-level stand
It's well known that Bandai has been putting considerable emphasis on stands across all grades recently. Stands have been evolving with various shapes, angles, and functions — and with the MG F91, they've finally taken it all the way to full diorama recreation level.
This kit includes a stand in the shape of the Rafflesia — the MA that serves as the final enemy in the film — and it's not just shaped like it for show. It comes out as a proper structure complete with a pilot figure inside the cockpit. It's got great volume, decent detail, and even the tentacles are recreated, making it genuinely possible to recreate a diorama scene straight out of the film.
The end result looks far more premium and luxurious than the plain black stands or launch pad-style stands of the past. :-)
6. Increased assembly difficulty
These were the issues that caused quite a stir when the kit first came out. Part of it is because the kit is small, but the entire body frame — inside and out — is built entirely from ABS, which makes it stiff, and the parts are tiny, so assembly can be a bit of a pain. There are parts that break easily if you're not careful, and some parts are just incredibly difficult to assemble — whether that's a tolerance issue or an ABS material issue, I'm not sure.
Bottom line, this is definitely not an easier build than previous MGs. Rather than saying Gundam F91 is hard to build, I'd say recent MGs have been a bit too assembly-friendly — but either way, the difficulty level has clearly gone up, and that means longer build times too. Was this Bandai's way of giving a wake-up call to Gunpla builders who've gotten too comfortable? ;;
I'll come back to this point below.
------------
As I mentioned above, this Gundam F91 clearly incorporates a number of new approaches that set it apart from previous kits. So it feels quite different in a lot of ways. I've already covered many of the MG Gundam F91's features above, but if I had to pick its biggest strength, it would be its "efficient articulation."
Like any modern kit, the MG Gundam F91's limbs fold completely, the waist has double-jointed movement, and the shoulders swing up and forward with ease. The reason I called it "efficient articulation" is this — when you look at individual joint ranges, there are plenty of kits with great articulation, but whether that articulation actually translates into great action poses is a separate matter entirely. In other words, a kit can have excellent individual joint movement but still look pretty underwhelming once you actually try to pose it.
With this MG Gundam F91, all those individual articulation points combine brilliantly — they mesh together in a truly "efficient" way. Simply put, the naturalness and dynamism of its action poses are outstanding. The frame style is similar to the MG Mobile Fighter G Gundam series kits, which are built around action-oriented frames, but this kit is clearly a step above even those. The waist articulation in particular — which has often been more or less useless in past kits — actually works effectively here in the MG Gundam F91.
Whatever pose you put it in, it looks natural, dynamic, and full of life — like it could leap into action at any moment. And on top of that, there's a premium stand included to help recreate those poses, which is just the cherry on top. I thought the MG Freedom and MG Aile Strike had good articulation too, but in terms of "naturalness" and "sense of life," the MG Gundam F91 is a cut above.
All these new approaches can be a good thing in their own way, but you can't overlook the fact that this kit has more assembly pitfalls than most other kits — and some of them can be pretty serious. Setting aside all the other minor issues, please make sure to check the link below about the knee cover problem before you start building.
See link > Assembly notes in photos (assembly page)
I already knew about the knee cover issue before I started building, but I went ahead and assembled it without any modifications (bold of me, I know?) to get a sense of just how bad the problem actually was. (Call it my experimental spirit..;) Sure enough, it was a frustration-meter-at-200% kind of problem.. Even accounting for kit variation, if you care about your kit at all, I strongly recommend sanding it down before assembly T_T. Other assembly notes that have been flagged are summarized separately at the bottom of the page above, so please check those out too.
Based on reports so far, it seems like there's some variation between individual kits when it comes to these assembly issues. Some people have no problems at all, while others find it literally impossible to assemble without some modification.. Either way, there may be some luck of the draw involved, or Bandai may make minor mold adjustments down the line — but I believe that as long as you're careful about the issues mentioned above, you should be fine. :-)
One other minor downside is the weak grip strength. The fingers don't hold well and tend to be loose — largely because the connection between the back of the hand and the palm parts is weak. You'll probably want to glue that section down, otherwise you'll keep having the index finger or thumb pop off. On top of that, the palm's weapon-holding mechanism isn't all that tight, so weapons tend to drop out constantly. It feels even more disappointing compared to how tight the rest of the body is.
The durability of the all-ABS joint structure without polycaps is reasonably reliable, but in my case, the ball joint above the waist felt noticeably weaker than the rest. Maybe it's because I disassembled and reassembled it so many times for the review, but when you move it too aggressively, it just pops right out;; Thankfully, the other joints seem like they won't loosen up easily under normal movement, so that's a relief.
Personally, the part of the MG Gundam F91 I still have the hardest time getting used to is this all-ABS joint structure throughout the body. Without the smooth feel you get from polycaps, there's a nagging sense of something missing — a 2% resistance, if you will. I'll definitely give credit where it's due for the improved joint strength, but I can't help wondering — did it really have to be this way? I think properly tuning polycap tolerances could have gotten you a pretty solid hold too.
The ¥3,200 price point felt a little odd at first, but when you consider how much content is packed in, it actually feels like a bargain. Looking at everything included, ¥3,500 would have been totally reasonable — so the fact that it's ¥3,200, seemingly untouched by inflation even after 10 years, is something you can genuinely call a good deal. :-)
Sure, a lot of people may have developed a love-hate relationship with this kit thanks to the early assembly issues, but as long as you know what to watch out for beforehand, it's a great kit with no major problems. In fact, in terms of frame design and articulation, this is hands-down the best MG out there. The score takes a few hits for some awkward and half-baked attempts at new ideas, but I want to give a round of applause to the Bandai developers for not settling for the safe and familiar, and continuing to push for something new. Just maybe don't go too overboard — take it one step at a time. :-)
* Many of the mold issues pointed out in this review appear to have been largely corrected around the time the MG Gundam F91 Harrison Madin Custom was released. So if you want a kit with the knee cover and other problems fixed, make sure to check whether you're getting a reissue or a first-run copy before buying. Of course, even if it is a first-run copy, as long as you go through this review carefully before building, it shouldn't be a big deal — so no need to stress too much. ^_^;
